Yes you can cut them off, and ONLY them.

That's where I had them placed at first. but then I started second guessing myself. thank you

Just clarifying... the BackPlane boards with Gold fingers will NOT pull Gold finger card? and they are BackPlane either with or without the Gold fingers? so it's OK to harvest the gold fingers off of those??? Thanks RT

Correct when they are that large they go as backplane. Removing the fingers gives you backplane plus fingers. ;)

Thanks! I did a little research/math...
I trimmed the gold fingers from 4 Backplane boards. 3 of them had standard fingers and one of them had longer fingers (3/8" +/-) the trimmed fingers off one with standard size fingers weighed 2.4G, the fingers off the one with longer fingers weighed 5.5G . total weight of the fingers from the 4 boards was 12.9G . at todays payout of $32 Lb for trimmed fingers which equals $.07 per Gram the 12.9G of fingers is worth @ $.90 and only took a couple cents of weight off the Backplane rate. so in Volume... not a bad gig.

One queston about trimming fingers, I made sure to trim very carefully and not get green board. but the gold fingers do not go all the way to the edge of the boards there is maybe 1/32" of naked board beyond the end of the fingers. does that edge need to be trimmed as well? if so, my numbers above are heavy RT

I'll post photo's of 'clean" fingers in a little bit.
